Jimmy Fallon’s “Lip Flip” must be stopped. It has to end. Sure, the technology that drives this particular ‘Tonight Show’ segment is vaguely impressive (there are lips! and then they get flipped!), and Fallon and his various guests appear to have a good time pretending to talk out of each other's mouths, but the final execution is so terrifying, so weird, that it can only do one thing: cause nightmares.

Please, Jimmy Fallon, we beg you, lay off the “Lip Flip”. Yes, we know you and guest Jennifer Aniston had a lot of fun last night, and your cracks about Bonnaroo and football were amusing for a time, but we've had enough. We're scared. Please show mercy.
